Music is another skill I have developed recently. It started during the process of making a visual novel. I realized that royalty music, while often good, could not encompass the emotions necessary for the narrative.
As I do not know any composers, I decided to learn it on my own. I do know some piano, after all, so how hard could it be?
Not easy, but by starting out with some samples at first to understand the tools used for music production, I built up my confidence and skillset.
